Resonators Procurement Notes

Verify the specific suffix and series designation against official Murata documentation to ensure compatibility with existing designs. Confirm that the required frequency tolerance and stability meet the target application's specifications before procurement. Check current availability status as this component may be subject to supply constraints or obsolescence notices.

Resonators Selection Notes

Select this component when a compact, cost-effective timing solution is required for low-to-medium frequency applications. Ensure the PCB layout accommodates the 3.20 x 1.30 mm footprint. Verify that the system's load capacitance requirements align with the internal 5 pF capacitor to maintain accurate frequency output without external components.

Resonators Part Context

This part belongs to the CERALOCK CSTCE series, which utilizes piezoelectric ceramic materials for resonance. It serves as an alternative to discrete crystal oscillator solutions where lower phase noise and higher cost sensitivity are acceptable. The series is widely used in general-purpose digital logic and microprocessor clock generation.

Resonators Replacement Considerations

CSTNE14M7V510000R0 is listed as a direct substitute by Murata, though it differs in frequency and package type. No other identical 18 MHz replacement is confirmed in public data.
